Выносной магнитный валкодер (пульт управления) для КВ-трансивера Xiegu G90.

Проект разработан на базе неблокирующих конечных автоматов (FSM) для воссоздания классического «аналогового» и тактильно приятного ощущения плавной настройки, которого так не хватает штатным энкодерам.

Vfo controller: common questions

What microcontroller does the Vfo controller use?

The Vfo controller is built around the STM32F102C8T6, from the STM32 family.

How big is the Vfo controller PCB?

The Vfo controller measures 56 × 50 mm, has 2 copper layers and is 1.59112 mm thick.

How many components are on the Vfo controller?

53 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Vfo controller design files?

From the xflyingcat/vfo_controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Vfo controller design in my own project?

Yes, under the terms of its MIT license, which xflyingcat chose for the repository.

Can I test firmware for the Vfo controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
